[stage] Use min-width/height props for min size

Browse Source 
Instead of shadowing these properties with different properties with the
same names on stage, actually use them. Behaviour should be identical,
except the minimum stage size can now be enforced by setting the
min-width/height properties as well as using the set_minimum_size
function.
